Abstract

A decoding method for decoding blocks of a picture part is disclosed that comprises :
- decoding a plurality of candidate sets of filter parameters from a bitstream;
- decoding for a current block of said picture an index identifying one of the candidate sets of filter parameters from said bitstream;
- decoding said current block from said bitstream; and
- filtering said decoded current block with the candidate set of filter parameters identified by said decoded index.
